To .all it may concem:

`Beitflmown that I, RUDOLPH ANDERS, a

citizen-of` the. United States, residing at Bridgeport,in the county of Fairfield and State of Connecticut, have invented a new and useful Airshi and I do hereby declare the following to be a full, clear, and exact description of the. invention, such us will enable others skilled in the art to which it appertains to make and use the same.

This invention belongs to the art of avration, and 'it Vrelates particularly to a new and useful aeroplane of the bi-plane type.

The-principal' object of the invention is the provision of a simple, eiiicient and practical-improved biplane, in which there 1s involved novel features of construction.

One of the features of this-improved biplane isthe lowering and elevating plane, which isfcentrally pivote'd' and so manipulated as to direct the biplane up ordown,

. while" the rudder in the rear is manipulated, so as tQfguide the craft to the right or the left.`

The invention comprises further features andv combination of parts, as hereinafter set forth, shown 'in the drawings and claimed.

Inftlie drawings: Figure 1 is a view in side elevation of a biplane constructed in accordance with the invention. Fig. 2 is a `plait-.view Fig. 3 isa transverse sectional View 'on line 3-3 ofFig.l 2. Fig. 4 is a transverse sectional view on line 4-f4 of Fig. v2.a Fig. 5 is a detail view of the means for manipulating the elevated plane. Fig. 6 is a sectional view on line6--6 of Fig. 5.

Fig. 7 is a detail'viewofgthe connection between-*the rudder and its-operating means.

Referring to "the drawings 1 designates a frame which is substantially triangular in plan' view vcomprises fthe upper and lower portions Sigrid =4`. `These-up er and lower portions 'y are fjgbraced relative y with regard tor oneanother bythe vertical bars 5 and the brac'erods' SL-Thisfframe may be constructed ofV vanysruitable material. The pperand lower vportions of'the frame are coveredwith areasjof. canvas' or other suit able material 7, tl'lsjproyiding the upper and lower planes#l @n the upper surface of the lower portion of the frame is a platform of any suitable-material 8 which supports any suitable type. of engine or other motor 9 having the usual drive shaft 10.. Mounted 1n bearings on the platform, for'- wardly and rearwardly of the frame are shafts 11 and 12. .These-,shafts are' provided with. suitablefclutch connections 13 with the ydrive shaft ofthe engine.

will permit the vshafts 11 and 12 to be thrown in and out of gearwith the drive shaftof the engine. Mounted on the rear end ofthe shaft 12 is a propeller 14.' The by the .operator while the others are for passengers. These seats are designated by the numerals 19 and 20. y 4

An elevating plane 21 is provided, which pivoted in the forward portion thereof, as at 22 so as to oscillate, whereby the craft may be directed downwardly or upwardly. The pivot shaft 22 of the elevatingplane is journaled in bearings ofthe standards 23. Projecting upwardlyv from thepivot shaft 22 is an arm 24,` to which is vconnected a rod- PatentediApr. 30, 1912.

The clutch connections are of a type, such as extends transversely of "the craft, and is provided with a laterally extending braced arm 31, which connects with the -rod 32,

which also threads through a wheel 33simi.

95 in the frame 34, Aand when manuallylmanigf' l' V lar to the wheel 26. The wheel33 :revolves `iulated the rudder 29 is thrown to thfli'ig or the left, by virtue of the rd connection.'

Extending longitudinally of the. frame and downwardly therefrom, is what maybe termed the `equilibrium plane orlkeel'f'fx' which is hinged to the framey This! may be oscillated by the means` 36,-37 d 38. The parts 36, 37 and 38 are similarv j the mechanism for manipulating the eletgating plane. The .object for permitting' keel to be oscillated, is to dispose thefcrtft in such a position as toi 'cause it to'liiake lon curved sweeps, onshortones. ff;

rom the foregoing 1t will be noted that,

there has been devised a novel, simple and eiiicient biplane, and one which has been found practical.

The invention having been set forth, what is claimed as new and useful is:

l. In an aeroplane, a frame of an elongated triangular contour in plan and having upper and lower spaced apart op ositely disposed planes correspondingin s ape to the contour of the frame, an elevating elongated equilibrium plane extending transversely of the frame and fulcrumed therein substantially midway of its width, and located approximately centrally between the upper and the lower frames, with substantially equal correspondingly shaped portions extending laterally upon either side of the frame,a keel equilibrium plane of elongated substantially triangular contour fulcrumed under the frame substantially midway of its width and adapted to oscillate laterally, a rudder equilibrium plane fulcrumed in a vertical position substantially at the rear of the frame to oscillate laterally, and like mechanisms, each of which is capable of being operated independently, to independently oscillate each equilibrium plane.

2. In an aeroplane, a frame of an elongated triangular contour in plan and having upper and lower spaced' apart oppositely disposed planes correspondin in shape to the contour of the frame, an e evating elongated equilibrium plane extending transversely of the frame and fulcrumed therein substantially midway of its width, and located approximately centrally between the upper and the lower frames, with substantially equal correspondingly shaped portions extending laterally upon either side of 40 the frame, a keel equilibrium plane of elongated substantially triangular contour fulcrumed under the frame substantially mdway of its width and adapted to oscillatc laterally, a rudder equilibrium plane .ful-
